Implementation of network security from the hardware level

Jumper on the state table carefully synchronized so that two firewalls at any time, contains the same information , the organic form of a hot start with high reliability real-time firewall system. When the primary firewall fails, the standby firewall in a very short period of time take over the work of the collapse of the main firewall . Firewall configuration is as follows ( the firewall does not stand out in Figure 1 successful ): firewall (config) # hasethearbeat-interfaceif3firewall (config) # haenable ∥ set heartbeat even in IDSVI ∥ enable hot standby function 3 network security is a conclusion can not be ignored Problems. With the continuous increase in network applications , the LAN connected to the Internet should take a strong security policy, to build complete network security system. Network interconnection devices , mainly from staff ,[link widoczny dla zalogowanych], focusing on the switches, routers, firewall related security-related configuration on the security of the hardware for the software to provide basic guarantees of security . On this basis , we can further in-depth discussion of software security.
